The present invention relates to microbial mannanases, more specifically to microbial enzymes exhibiting mannanase activity as their major enzymatic activity in the neutral and alkaline pH ranges; to a method of producing such enzymes; and to methods for using such enzymes in the paper and pulp, textile, oil drilling, cleaning, laundering, detergent and cellulose fiber processing industries.

BACKGROUND OF THE INVENTION

Mannan containing polysaccharides are a major component of the hemicellulose fraction in woods and endosperm in many leguminous seeds and in some mature seeds of non-leguminous plants. Essentially unsubstituted linear beta-1,4-mannan is found in some non-leguminous plants. Unsubstituted beta-1,4-mannan which is present e.g. in ivory nuts resembles cellulose in the conformation of the individual polysaccharide chains, and is water-insoluble. In leguminous seeds, water-soluble galactomannan is the main storage carbohydrate comprising up to 20% of the total dry weight. Galactomannans have a linear beta-1,4-mannan backbone substituted with single alpha-1,6-galactose, optionally substituted with acetyl groups. Mannans are also found in several monocotyledonous plants and are the most abundant polysaccharides in the cell wall material in palm kernel meal. Glucomannans are linear polysaccharides with a backbone of beta-1,4-linked mannose and glucose alternating in a more or less regular manner, the backbone optionally being substituted with galactose and/or acetyl groups. Mannans, galactomannans, glucomannans and galactoglucomannans (i.e. glucomannan backbones with branched galactose) contribute to more than 50% of the softwood hemicellulose. Moreover, the cellulose of many red algae contains a significant amount of mannose.

Mannanases have been identified in several Bacillus organisms. For example, Talbot et al., Appl. Environ. Microbiol., Vol.56, No. 11, pp. 3505-3510 (1990) describes a beta-mannanase derived from Bacillus stearothermophilus in dimer form having molecular weight of 162 kDa and an optimum pH of 5.5-7.5. Mendoza et al., World J. Microbiol. Biotech., Vol. 10, No. 5, pp. 551-555 (1994) describes a beta-mannanase derived from Bacillus subtilis having a molecular weight of 38 kDa, an optimum activity at pH 5.0 and 55° C. and a pI of 4.8. JP-A-03047076 discloses a beta-mannanase derived from Bacillus sp., having a molecular weight of 37±3 kDa measured by gel filtration, an optimum pH of 8-10 and a pI of 5.3-5.4. JP-A-63056289 describes the production of an alkaline, thermostable beta-mannanase which hydrolyses beta-1,4-D-mannopyranoside bonds of e.g. mannans and produces manno-oligosaccharides. JP-A-63036775 relates to the Bacillus microorganism FERM P-8856 which produces beta-mannanase and beta-mannosidase at an alkaline pH. JP-A-08051975 discloses alkaline beta-mannanases from alkalophilic Bacillus sp. AM-001 having molecular weights of 43±3 kDa and 57±3 kDa and optimum pH of 8-10. A purified mannanase from Bacillus amyloliquefaciens useful in the bleaching of pulp and paper and a method of preparation thereof is disclosed in WO 97/11164. WO 91/18974 describes a hemicellulase such as a glucanase, xylanase or mannanase active at an extreme pH and temperature. WO 94/25576 discloses an enzyme from Aspergillus aculeatus, CBS 101.43, exhibiting mannanase activity which may be useful for degradation or modification of plant or algae cell wall material. WO 93/24622 discloses a mannanase isolated from Trichoderma reseei useful for bleaching lignocellulosic pulps.

WO 95/35362 discloses cleaning compositions containing plant cell wall degrading enzymes having pectinase and/or hemicellulase and optionally cellulase activity for the removal of stains of vegetable origin and further discloses an alkaline mannanase from the strain C11SB.G17.

It is an object of the present invention to provide a novel and efficient enzyme exhibiting mannanase activity also in the alkaline pH range, e.g. when applied in cleaning compositions or different industrial processes.

DEFINITIONS

Prior to discussing this invention in further detail, the following terms will first be defined.

The term “ortholog” (or “species homolog”) denotes a polypeptide or protein obtained from one species that has homology to an analogous polypeptide or protein from a different species.

The term “paralog” denotes a polypeptide or protein obtained from a given species that has homology to a distinct polypeptide or protein from that same species.

The term “expression vector” denotes a DNA molecule, linear or circular, that comprises a segment encoding a polypeptide of interest operably linked to additional segments that provide for its transcription. Such additional segments may include promoter and terminator sequences, and may optionally include one or more origins of replication, one or more selectable markers, an enhancer, a polyadenylation signal, and the like. Expression vectors are generally derived from plasmid or viral DNA, or may contain elements of both. The expression vector of the invention may be any expression vector that is conveniently subjected to recombinant DNA procedures, and the choice of vector will often depend on the host cell into which the vector is to be introduced. Thus, the vector may be an autonomously replicating vector, i.e. a vector which exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g. a plasmid. Alternatively, the vector may be one which, when introduced into a host cell, is integrated into the host cell genome and replicated together with the chromosome(s) into which it has been integrated.

The term “recombinant expressed” or “recombinantly expressed” used herein in connection with expression of a polypeptide or protein is defined according to the standard definition in the art. Recombinantly expression of a protein is generally performed by using an expression vector as described immediately above.

The term “isolated”, when applied to a polynucleotide molecule, denotes that the polynucleotide has been removed from its natural genetic milieu and is thus free of other extraneous or unwanted coding sequences, and is in a form suitable for use within genetically engineered protein production systems. Such isolated molecules are those that are separated from their natural environment and include cDNA and genomic clones. Isolated DNA molecules of the present invention are free of other genes with which they are ordinarily associated, but may include naturally occurring 5′ and 3′ untranslated regions such as promoters and terminators. The identification of associated regions will be evident to one of ordinary skill in the art (see for example, Dynan and Tijan, Nature 316:774-78, 1985). The term “an isolated polynucleotide” may alternatively be termed “a cloned polynucleotide”.

When applied to a protein/polypeptide, the term “isolated” indicates that the protein is found in a condition other than its native environment. In a preferred form, the isolated protein is substantially free of other proteins, particularly other homologous proteins (i.e. “homologous impurities” (see below)). It is preferred to provide the protein in a greater than 40% pure form, more preferably greater than 60% pure form.

Even more preferably it is preferred to provide the protein in a highly purified form, i.e., greater than 80% pure, more preferably greater than 95% pure, and even more preferably greater than 99% pure, as determined by SDS-PAGE.

The term “isolated protein/polypeptide may alternatively be termed “purified protein/polypeptide”.

The term “homologous impurities” means any impurity (e.g. another polypeptide than the polypeptide of the invention) which originate from the homologous cell where the polypeptide of the invention is originally obtained from.

The term “obtained from” as used herein in connection with a specific microbial source, means that the polynucleotide and/or polypeptide is produced by the specific source (homologous expression), or by a cell in which a gene from the source have been inserted (heterologous expression).

The term “operably linked”, when referring to DNA segments, denotes that the segments are arranged so that they function in concert for their intended purposes, e.g. transcription initiates in the promoter and proceeds through the coding segment to the terminator.

The term “polynucleotide” denotes a single- or double-stranded polymer of deoxyribonucleotide or ribonucleotide bases read from the 5′ to the 3′ end. Polynucleotides include RNA and DNA, and may be isolated from natural sources, synthesized in vitro, or prepared from a combination of natural and synthetic molecules.

The term “complements of polynucleotide molecules” denotes polynucleotide molecules having a complementary base sequence and reverse orientation as compared to a reference sequence. For example, the sequence 5′ ATGCACGGG 3′ is complementary to 5′ CCCGTGCAT 3′.

The term “degenerate nucleotide sequence” denotes a sequence of nucleotides that includes one or more degenerate codons (as compared to a reference polynucleotide molecule that encodes a polypeptide). Degenerate codons contain different triplets of nucleotides, but encode the same amino acid residue (i.e., GAU and GAC triplets each encode Asp).

The term “promoter” denotes a portion of a gene containing DNA sequences that provide for the binding of RNA polymerase and initiation of transcription. Promoter sequences are commonly, but not always, found in the 5′ non-coding regions of genes.

The term “secretory signal sequence” denotes a DNA sequence that encodes a polypeptide (a “secretory peptide”) that, as a component of a larger polypeptide, directs the larger polypeptide through a secretory pathway of a cell in which it is synthesized. The larger peptide is commonly cleaved to remove the secretory peptide during transit through the secretory pathway.

The term “enzyme core” denotes a single domain enzyme which may or may not have been modified or altered, but which has retained its original activity; the catalytic domain as known in the art has remained intact and functional.

By the term “linker” or “spacer” is meant a polypeptide comprising at least two amino acids which may be present between the domains of a multidomain protein, for example an enzyme comprising an enzyme core and a binding domain such as a cellulose binding domain (CBD) or any other enzyme hybrid, or between two proteins or polypeptides expressed as a fusion polypeptide, for example a fusion protein comprising two core enzymes. For example, the fusion protein of an enzyme core with a CBD is provided by fusing a DNA sequence encoding the enzyme core, a DNA sequence encoding the linker and a DNA sequence encoding the CBD sequentially into one open reading frame and expressing this construct.

The term “mannanase” or “galactomannanase” denotes a mannanase enzyme defined according to the art as officially being named mannan endo-1,4-beta-mannosidase and having the alternative names beta-mannanase and endo-1,4-mannanase and catalysing hydrolyses of 1,4-beta-D-mannosidic linkages in mannans, galactomannans, glucomannans, and galactoglucomannans which enzyme is classified according to the Enzyme Nomenclature as EC 3.2.1.78.

DETAILED DESCRIPTION OF THE INVENTION

HOW TO USE A SEQUENCE OF THE INVENTION TO GET OTHER RELATED SEQUENCES: The disclosed sequence information herein relating to a polynucleotide sequence encoding a mannanase of the invention can be used as a tool to identify other homologous mannanases. For instance, polymerase chain reaction (PCR) can be used to amplify sequences encoding other homologous mannanases from a variety of microbial sources, in particular of different Bacillus species.

Assay for Activity Test

A polypeptide of the invention having mannanase activity may be tested for mannanase activity according to standard test procedures known in the art, such as by applying a solution to be tested to 4 mm diameter holes punched out in agar plates containing 0.2% AZCL galactomannan (carob), i.e. substrate for the assay of endo-1,4-beta-D-mannanase available as CatNo.I-AZGMA from the company Megazyme.

Polynucleotides

Within preferred embodiments of the invention an isolated polynucleotide of the invention will hybridize to similar sized regions of SEQ ID NO: 1, or a sequence complementary thereto, under at least medium stringency conditions.

In particular polynucleotides of the invention will hybridize to a denatured double-stranded DNA probe comprising either the full sequence shown in SEQ ID NO:1 or a partial sequence comprising the segment shown in positions 91-990 of SEQ ID NO:1 which segment encodes for the catalytically active domain or enzyme core of the mannanase of the invention or any probe comprising a subsequence shown in positions 91-990 of SEQ ID NO:1 which subsequence has a length of at least about 100 base pairs under at least medium stringency conditions, but preferably at high stringency conditions as described in detail below. Suitable experimental conditions for determining hybridization at medium, or high stringency between a nucleotide probe and a homologous DNA or RNA sequence involves presoaking of the filter containing the DNA fragments or RNA to hybridize in 5×SSC (Sodium chloride/Sodium citrate, Sambrook et al. 1989) for 10 min, and prehybridization of the filter in a solution of 5×SSC, 5×Denhardt's solution (Sambrook et al. 1989), 0.5% SDS and 100 μg/ml of denatured sonicated salmon sperm DNA (Sambrook et al. 1989), followed by hybridization in the same solution containing a concentration of 10 ng/ml of a random-primed (Feinberg, A. P. and Vogelstein, B. (1983) Anal. Biochem. 132:6-13), 32P-dCTP-labeled (specific activity higher than 1×10⁹ cpm/μg) probe for 12 hours at ca. 45° C. The filter is then washed twice for 30 minutes in 2×SSC, 0.5% SDS at least 60° C. (medium stringency), still more preferably at least 65° C. (medium/high stringency), even more preferably at least 70° C. (high stringency), and even more preferably at least 75° C. (very high stringency).

As previously noted, the isolated polynucleotides of the present invention include DNA and RNA. Methods for isolating DNA and RNA are well known in the art. DNA and RNA encoding genes of interest can be cloned in Gene Banks or DNA libraries by means of methods known in the art.

Polynucleotides encoding polypeptides having mannanase activity of the invention are then identified and isolated by, for example, hybridization or PCR.

Species homologues of a polypeptide with mannanase activity of the invention can be cloned using information and compositions provided by the present invention in combination with conventional cloning techniques. For example, a DNA sequence of the present invention can be cloned using chromosomal DNA obtained from a cell type that expresses the protein. Suitable sources of DNA can be identified by probing Northern or Southern blots with probes designed from the sequences disclosed herein. A library is then prepared from chromosomal DNA of a positive cell line. A DNA sequence of the invention encoding an polypeptide having mannanase activity can then be isolated by a variety of methods, such as by probing with probes designed from the sequences disclosed in the present specification and claims or with one or more sets of degenerate probes based on the disclosed sequences. A DNA sequence of the invention can also be cloned using the polymerase chain reaction, or PCR (Mullis, U.S. Pat. No. 4,683,202), using primers designed from the sequences disclosed herein. Within an additional method, the DNA library can be used to transform or transfect host cells, and expression of the DNA of interest can be detected with an antibody (mono-clonal or polyclonal) raised against the mannanase cloned from B.sp, expressed and purified as described in Materials and Methods and Example 1, or by an activity test relating to a polypeptide having mannanase activity.

See, in general Ford et al., Protein Expression and Purification 2: 95-107, 1991, which is incorporated herein by reference. DNAs encoding affinity tags are available from commercial suppliers (e.g., Pharmacia Biotechs, Piscataway, N.J.; New England Biolabs, Beverly, Mass.).

However, even though the changes described above preferably are of a minor nature, such changes may also be of a larger nature such as fusion of larger polypeptides of up to 300 amino acids or more both as amino- or carboxyl-terminal extensions to a Mannanase polypeptide of the invention.

TABLE 1 Conservative amino acid substitutions Basic: arginine lysine histidine Acidic: glutamic acid aspartic acid Polar: glutamine asparagine Hydrophobic: leucine isoleucine valine Aromatic: phenylalanine tryptophan tyrosine Small: glycine alanine serine threonine methionine

In addition to the 20 standard amino acids, non-standard amino acids (such as 4-hydroxyproline, 6-N-methyl lysine, 2-aminoisobutyric acid, isovaline and a-methyl serine) may be substituted for amino acids residues of a polypeptide according to the invention. A limited number of non-conservative amino acids, amino acids that are not encoded by the genetic code, and unnatural amino acids may be substituted for amino acid residues. “Unnatural amino acids” have been modified after protein synthesis, and/or have a chemical structure in their side chain(s) different from that of the standard amino acids. Unnatural amino acids can be chemically synthesized, or preferably, are commercially available, and include pipecolic acid, thiazolidine carboxylic acid, dehydroproline, 3- and 4-methylproline, and 3,3-dimethylproline.

Essential amino acids in the mannanase polypeptides of the present invention can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, Science 244: 1081-1085, 1989). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for biological activity (i.e mannanase activity) to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., J. Biol. Chem. 271:4699-4708, 1996. The active site of the enzyme or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., Science 255:306-312, 1992; Smith et al., J. Mol. Biol. 224:899-904, 1992; Wlodaver et al., FEBS lett. 309:59-64, 1992. The identities of essential amino acids can also be inferred from analysis of homologies with polypeptides which are related to a polypeptide according to the invention.

Multiple amino acid substitutions can be made and tested using known methods of mutagenesis, recombination and/or shuffling followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer (Science 241:53-57, 1988), Bowie and Sauer (Proc. Natl. Acad. Sci. USA 86: 2152-2156, 1989), WO95/17413, or WO 95/22625. Briefly, these authors disclose methods for simultaneously randomizing two or more positions in a polypeptide, or recombination/shuffling of different mutations (WO95/17413, WO95/22625), followed by selecting for functional a polypeptide, and then sequencing the mutagenized polypeptides to determine the spectrum of allowable substitutions at each position. Other methods that can be used include phage display (e.g., Lowman et al., Biochem. 30:10832-10837, 1991; Ladner et al., U.S. Pat. No. 5,223,409; Huse, WIPO Publication WO 92/06204) and region-directed mutagenesis (Derbyshire et al., Gene 46:145, 1986; Ner et al., DNA 7:127, 1988).

Mutagenesis/shuffling methods are disclosed above can be combined with high-throughput, automated screening methods to detect activity of cloned, mutagenized polypeptides in host cells. Mutagenized DNA molecules that encode active polypeptides can be recovered from the host cells and rapidly sequenced using modern equipment. These methods allow the rapid determination of the importance of individual amino acid residues in a polypeptide of interest, and can be applied to polypeptides of unknown structure.

Using the methods discussed above, one of ordinary skill in the art can identify and/or prepare a variety of polypeptides that are substantially homologous to residues 32-330 or 32-490 of SEQ ID NO:2; or to residues 32-344 or 32-494 of SEQ ID NO:6; or to residues 32-362 or 32-586 of SEQ ID NO:10; or to residues 33-331 of SEQ ID NO:12; or to residues 166-488 or 22-488 of SEQ ID NO:14, or to residues 68-369 or 32-369 of SEQ ID NO:16; or to residues 1-305 of SEQ ID NO:18; or to residues 1-132 of SEQ ID NO:20; or to residues 29-320 of SEQ ID NO:22; or to residues 29-188 of SEQ ID NO:24; or to residues 301-625 or 30-625 of SEQ ID NO:26; or to residues 166-496 or 38-496 of SEQ ID NO:28; or to residues 26-361 of SEQ ID NO:30; or to residues 593-903 or 23-903 of SEQ ID NO:32 and retain the mannanase activity of the wild-type protein.

The mannanase enzyme of the invention may, in addition to the enzyme core comprising the catalytically domain, also comprise a cellulose binding domain (CBD), the cellulose binding domain and enzyme core (the catalytically active domain) of the enzyme being operably linked. The cellulose binding domain (CBD) may exist as an integral part of the encoded enzyme, or a CBD from another origin may be introduced into the mannan degrading enzyme thus creating an enzyme hybrid. In this context, the term “cellulose-binding domain” is intended to be understood as defined by Peter Tomme et al. “Cellulose-Binding Domains: Classification and Properties” in “Enzymatic Degradation of Insoluble Carbohydrates”, John N. Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618, 1996. This definition classifies more than 120 cellulose-binding domains into 10 families (I-X), and demonstrates that CBDs are found in various enzymes such as cellulases, xylanases, mannanases, arabinofuranosidases, acetyl esterases and chitinases. CBDs have also been found in algae, e.g. the red alga Porphyra purpurea as a non-hydrolytic polysaccharide-binding protein, see Tomme et al., op.cit. However, most of the CBDs are from cellullases and yxlanases, CBDs are found at the N and C termini of proteins or are internal. Enzyme hybrids are known in the art, see e.g. WO 90/00609 and WO 95/16782, and may be prepared by transforming into a host cell a DNA construct comprising at least a fragment of DNA encoding the cellulose-binding domain ligated, with or without a linker, to a DNA sequence encoding the mannan degrading enzyme and growing the host cell to express the fused gene. Enzyme hybrids may be described by the following formula:

CBD−MR−X

wherein CBD is the N-terminal or the C-terminal region of an amino acid sequence corresponding to at least the cellulose-binding domain; MR is the middle region (the linker), and may be a bond, or a short linking group preferably of from about 2 to about 100 carbon atoms, more preferably of from 2 to 40 carbon atoms; or is preferably from about 2 to to about 100 amino acids, more preferably of from 2 to 40 amino acids; and X is an N-terminal or C-terminal region of the mannanase of the invention. SEQ ID NO:4 discloses the amino acid sequence of an enzyme hybrid of a mannanase enzyme core and a CBD.

Preferably, the mannanase enzyme of the present invention has its maximum catalytic activity at a pH of at least 7, more preferably of at least 8, more preferably of at least 8.5, more preferably of at least 9, more preferably of at least 9.5, more preferably of at least 10, even more preferably of at least 10.5, especially of at least 11; and preferably the maximum activity of the enzyme is obtained at a temperature of at least 40° C., more preferably of at least 50° C., even more preferably of at least 55° C.

Preferably, the cleaning composition of the present invention provides, eg when used for treating fabric during a washing cycle of a machine washing process, a washing solution having a pH typically between about 8 and about 10.5. Typically, such a washing solution is used at temperatures between about 20° C. and about 95° C., preferably between about 20° C. and about 60° C., preferably between about 20° C. and about 50° C.

Protein Production

The proteins and polypeptides of the present invention, including full-length proteins, fragments thereof and fusion proteins, can be produced in genetically engineered host cells according to conventional techniques. Suitable host cells are those cell types that can be transformed or transfected with exogenous DNA and grown in culture, and include bacteria, fungal cells, and cultured higher eukaryotic cells. Bacterial cells, particularly cultured cells of gram-positive organisms, are preferred. Gram-positive cells from the genus of Bacillus are especially preferred, such as from the group consisting of Bacillus subtilis, Bacillus lentus, Bacillus clausii, Bacillus agaradhaerens, Bacillus brevis, Bacillus stearothermophilus, Bacillus alkalophilus, Bacillus amyloliquefaciens, Bacillus coagulans, Bacillus circulans, Bacillus lautus, Bacillus thuringiensis, Bacillus licheniformis, and Bacillus sp., in particular Bacillus sp. I633, Bacillus sp. AAI12, Bacillus clausii, Bacillus agaradhaerens and Bacillus licheniformis.

In another preferred embodiment, the host cell is a fungal cell. “Fungi” as used herein includes the phyla Ascomycota, Basidiomycota, Chytridiomycota, and Zygomycota (as defined by Hawksworth et al., In, Ainsworth and Bisby's Dictionary of The Fungi, 8 th edition, 1995, CAB International, University Press, Cambridge, UK) as well as the Oomycota (as cited in Hawksworth et al., 1995, supra, page 171) and all mitosporic fungi (Hawksworth et al., 1995, supra). Representative groups of Ascomycota include, e.g., Neurospora, Eupenicillium (=Penicillium), Emericella (=Aspergillus), Eurotium (=Aspergillus), and the true yeasts listed above. Examples of Basidiomycota include mushrooms, rusts, and smuts. Representative groups of Chytridiomycota include, e.g., Allomyces, Blastocladiella, Coelomomyces, and aquatic fungi. Representative groups of Oomycota include, e.g., Saprolegniomycetous aquatic fungi (water molds) such as Achlya. Examples of mitosporic fungi include Aspergillus, Penicilluim, Candida, and Alternaria. Representative groups of Zygomycota include, e.g., Rhizopus and Mucor.

In yet another preferred embodiment, the fungal host cells is a filamentous fungal cell. “Filamentous fungi” include all filamentous forms of the subdivision Eumycota and Oomycota (as defined by Hawksworth et al., 1995, supra). In a more preferred embodiment, the filamentous fungal host cell is a cell of a species of, but not limited to, Acremonium, Aspergillus, Fusarium, Humicola, Mucor, Myceliophthora, Neurospora, Penicillium, Thielavia, Tolypocladium, and Trichoderma or a teleomorph or synonym thereof.

In particular, the cell may belong to a species of Trichoderma, preferably Trichoderma harzianum or Trichoderma reesei, or a species of Aspergillus, most preferably Aspergillus oryzae or Aspergillus niger, or a species of Fusarium, most preferably a Fusarium sp. having the identifying characteristic of Fusarium ATCC 20334, as further described in PCT/US/95/07743.

Fungal cells may be transformed by a process involving protoplast formation, transformation of the protoplasts, and regeneration of the cell wall in a manner known per se. Suitable procedures for transformation of Aspergillus host cells are described in EP 238 023 and Yelton et al., 1984, Proceedings of the National Academy of Sciences USA 81:1470-1474. A suitable method of transforming Fusarium species is described by Malardier et al., 1989, Gene 78:147-156 or in copending U.S. Ser. No. 08/269,449. Yeast may be transformed using the procedures described by Becker and Guarente, In Abelson, J. N. and Simon, M. I., editors, Guide to Yeast Genetics and Molecular Biology, Methods in Enzymology, Volume 194, pp 182-187, Academic Press, Inc., New York; Ito et al., 1983, Journal of Bacteriology 153:163; and Hinnen et al., 1978, Proceedings of the National Academy of Sciences USA 75:1920. Mammalian cells may be transformed by direct uptake using the calcium phosphate precipitation method of Graham and Van der Eb (1978, Virology 52:546).

Techniques for manipulating cloned DNA molecules and introducing exogenous DNA into a variety of host cells are disclosed by Sambrook et al., Molecular Cloning: A Laboratory Manual, 2 nd ed., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989; Ausubel et al. (eds.), Current Protocols in Molecular Biology, John Wiley and Sons, Inc., N.Y. 1987; and “Bacillus subtilis and Other Gram-Positive Bacteria”, Sonensheim et al., 1993, American Society for Microbiology, Washington D.C., which are incorporated herein by reference.

In general, a DNA sequence encoding a mannanase of the present invention is operably linked to other genetic elements required for its expression, generally including a transcription promoter and terminator within an expression vector. The vector will also commonly contain one or more selectable markers and one or more origins of replication, although those skilled in the art will recognize that within certain systems selectable markers may be provided on separate vectors, and replication of the exogenous DNA may be provided by integration into the host cell genome. Selection of promoters, terminators; selectable markers, vectors and other elements is a matter of routine design within the level of ordinary skill in the art. Many such elements are described in the literature and are available through commercial suppliers.

To direct a polypeptide into the secretory pathway of a host cell, a secretory signal sequence (also known as a leader sequence, prepro sequence or pre sequence) is provided in the expression vector. The secretory signal sequence may be that of the polypeptide, or may be derived from another secreted protein or synthesized de novo. Numerous suitable secretory signal sequences are known in the art and reference is made to “Bacillus subtillis and Other Gram-Positive Bacteria”, Sonensheim et al., 1993, American Society for Microbiology, Washington D.C.; and Cutting, S. M. (eds.) “Molecular Biological Methods for Bacillus”, John Wiley and Sons, 1990, for further description of suitable secretory signal sequences especially for secretion in a Bacillus host cell. The secretory signal sequence is joined to the DNA sequence in the correct reading frame. Secretory signal sequences are commonly positioned 5′ to the DNA sequence encoding the polypeptide of interest, although certain signal sequences may be positioned elsewhere in the DNA sequence of interest (see, e.g., Welch et al., U.S. Pat. No. 5,037,743; Holland et al., U.S. Pat. No. 5,143,830).

The expression vector of the invention may be nay expression vector that is conveniently subjected to recombinant DNA procedures, and the choice of vector will often depend on the host cell into which the vector it is to be introduced. Thus, the vector may be an autonomously replicating vector, i.e. a vector which exists as an extrachromosomal entity, the replication of which is independent of chromosomal replication, e.g. a plasmid, Alternatively, the vector may be one which, when introduced into a host cell, is integrated into the host cell genome and replicated together with the chromosome(s) into which it has been integrated.

Examples of suitable promoters for use in filamentous fungus host cells are, e.g. the ADH3 promoter (McKnight et al., The EMBO J. 4 (1985), 2093-2099) or the tpiA promoter. Examples of other useful promoters are those derived from the gene encoding Aspergillus oryzae TAKA amylase, Rhizomucor miehei aspartic proteinase, Aspergillus niger neutral a-amylase, Aspergillus niger acid stable a-amylase, Aspergillus niger or Aspergillus awamori glucoamylase (gluA), Rhizomucor miehei lipase, Aspergillus oryzae alkaline protease, Aspergillus oryzae triose phosphate isomerase or Aspergillus nidulans acetamidase.

Transformed or transfected host cells are cultured according to conventional procedures in a culture medium containing nutrients and other components required for the growth of the chosen host cells. A variety of suitable media, including defined media and complex media, are known in the art and generally include a carbon source, a nitrogen source, essential amino acids, vitamins and minerals. Media may also contain such components as growth factors or serum, as required. The growth medium will generally select for cells containing the exogenously added DNA by, for example, drug selection or deficiency in an essential nutrient which is complemented by the selectable marker carried on the expression vector or co-transfected into the host cell.

Protein Isolation

When the expressed recombinant polypeptide is secreted the polypeptide may be purified from the growth media. Preferably the expression host cells are removed from the media before purification of the polypeptide (e.g. by centrifugation).

When the expressed recombinant polypeptide is not secreted from the host cell, the host cell are preferably disrupted and the polypeptide released into an aqueous “extract” which is the first stage of such purification technique. Preferably the expression host cells are collected from the media before the cell disruption (e.g. by centrifugation).

The cell disruption may be performed by conventional techniques such as by lysozyme digestion or by forcing the cells through high pressure. See (Robert K. Scobes, Protein Purification, Second edition, Springer-Verlag) for further description of such cell disruption techniques.

Whether or not the expressed recombinant polypeptides (or chimeric polypeptides) is secreted or not it can be purified using fractionation and/or conventional purification methods and media.

Ammonium sulfate precipitation and acid or chaotrope extraction may be used for fractionation of samples. Exemplary purification steps may include hydroxyapatite, size exclusion, FPLC and reverse-phase high performance liquid chromatography. Suitable anion exchange media include derivatized dextrans, agarose, cellulose, polyacrylamide, specialty silicas, and the like. PEI, DEAE, QAE and Q derivatives are preferred, with DEAE Fast-Flow Sepharose (Pharmacia, Piscataway, N.J.) being particularly preferred. Exemplary chromatographic media include those media derivatized with phenyl, butyl, or octyl groups, such as Phenyl-Sepharose FF (Pharmacia), Toyopearl butyl 650 (Toso Haas, Montgomerville, Pa.), Octyl-Sepharose (Pharmacia) and the like; or polyacrylic resins, such as Amberchrom CG 71 (Toso Haas) and the like. Suitable solid supports include glass beads, silica-based resins, cellulosic resins, agarose beads, cross-linked agarose beads, polystyrene beads, cross-linked polyacrylamide resins and the like that are insoluble under the conditions in which they are to be used. These supports may be modified with reactive groups that allow attachment of proteins by amino groups, carboxyl groups, sulfhydryl groups, hydroxyl groups and/or carbohydrate moieties. Examples of coupling chemistries include cyanogen bromide activation, N-hydroxysuccinimide activation, epoxide activation sulfhydryl activation, hydrazide activation, and carboxyl and amino derivatives for carbodiimide coupling chemistries. These and other solid media are well known and widely used in the art, and are available from commercial suppliers.

Selection of a particular method is a matter of routine design and is determined in part by the properties of the chosen support. See, for example, Affinity Chromatography: Principles& Methods, Pharmacia LKB Biotechnology, Uppsala, Sweden, 1988.

Polypeptides of the invention or fragments thereof may also be prepared through chemical synthesis. Polypeptides of the invention may be monomers or multimers; glycosylated or non-glycosylated; pegylated or non-pegylated; and may or may not include an initial methionine amino acid residue.

Alternatively, the DNA encoding the mannan or galactomannan-degrading enzyme of the invention may, in accordance with well-known procedures, conveniently be cloned from a suitable source, such as any of the above mentioned organisms, by use of synthetic ologonucleotide probes prepared on the basis of the DNA sequence obtainable from the plasmid present any of the strains Escherichia coli DSM 12197, DSM 12180, DSM 12433, DSM 12441, DSM 9984, DSM 12432, DSM 12436, DSM 12846, DSM 12847, DSM 12848, DSM 12849, DSM 12850, DSM 12851 and DSM 12852.

Accordingly, the polynucleotide molecule of the invention may be isolated from any of Escherichia coli, DSM 12197, DSM 12180, DSM 12433, DSM 12441, DSM 9984, DSM 12432, DSM 12436, DSM 12846, DSM 12847, DSM 12848, DSM 12849, DSM 12850, DSM 12851 and DSM 12852, in which the plasmid obtained by cloning such as described above is deposited.

In the present context, the term “enzyme preparation” is intended to mean either a conventional enzymatic fermentation product, possibly isolated and purified, from a single species of a microorganism, such preparation usually comprising a number of different enzymatic activities; or a mixture of monocomponent enzymes, preferably enzymes derived from bacterial or fungal species by using conventional recombinant techniques, which enzymes have been fermented and possibly isolated and purified separately and which may originate from different species, preferably fungal or bacterial species or the fermentation product of a microorganism which acts as a host cell for expression of a recombinant mannanase, but which microorganism simultaneously produces other enzymes, e.g. pectin degrading enzymes, proteases, or cellulases, being naturally occurring fermentation products of the microorganism, i.e. the enzyme complex conventionally produced by the corresponding naturally occurring microorganism.

The mannanase preparation of the invention may further comprise one or more enzymes selected from the group consisting of proteases, cellulases (endo-β-1,4-glucanases), β-glucanases (endo-β-1,3 (4)-glucanases), lipases, cutinases, peroxidases, laccases, amylases, glucoamylases, pectinases, reductases, oxidases, phenoloxidases, ligninases, pullulanases, hemicellulases, pectate lyases, xyloglucanases, xylanases, pectin acetyl esterases, rhamnogalacturonan acetyl esterases, polygalacturonases, rhamnogalacturonases, pectin lyases, pectin methylesterases, cellobiohydrolases, transglutaminanses; or mixtures thereof. In a preferred embodiment, one or more of all enzymes in the preparation is produced by using recombinant techniques, i.e. the enzymes(s) is/are mono-component enzyme(s) which is/are mixed with the other enzyme(s) to form an enzyme preparation with the desired enzyme blend.

In another aspect, the present invention also relates to a method of producing the enzyme preparation of the invention, the method comprising culturing a microorganism, eg a wild-type strain, capable of producing the mannanase under conditions permitting the production of the enzyme, and recovering the enzyme from the culture. Culturing may be carried out using conventional fermentation techniques, e.g. culturing in shake flasks or fermentors with agitation to ensure sufficient aeration on a growth medium inducing production of the mannanase enzyme. The growth medium may contain a conventional N-source such as peptone, yeast extract or casamino acids, a reduced amount of a conventional C-source such as dextrose or sucrose, and an inducer such as guar gum or locust beam gum. The recovery may be carried out using conventional techniques, e.g. separation of bio-mass and supernatant by centrifugation or filtration, recovery of the supernatant or disruption of cells if the enzyme of interest is intracellular, perhaps followed by further purification as described in EP 0 406 314 or by crystallization as described in WO 97/15660.

Examples of useful bacteria producing the enzyme or the enzyme preparation of the invention are Gram positive bacteria, preferably from the Bacillus/Lactobacillus subdivision, preferably a strain from the genus Bacillus, more preferably a strain of Bacillus sp.

In yet another aspect, the present invention relates to an isolated mannanase having the properties described above and which is free from homologous impurities, and is produced using conventional recombinant techniques.

Immunological Cross-Reactivity

Polyclonal antibodies to be used in determining immunological cross-reactivity may be prepared by use of a purified mannanase enzyme. More specifically, antiserum against the mannanase of the invention may be raised by immunizing rabbits (or other rodents) according to the procedure described by N. Axelsen et al. in: A Manual of Quantitative Immunoelectrophoresis, Blackwell Scientific Publications, 1973, Chapter 23, or A. Johnstone and R. Thorpe, Immunochemistry in Practice, Blackwell Scientific Publications, 1982 (more specifically p. 27-31). Purified immunoglobulins may be obtained from the antisera, for example by salt precipitation (NH₄)₂ SO₄), followed by dialysis and ion exchange chromatography, e.g. on DEAE-Sephadex. Immunochemical characterization of proteins may be done either by Outcherlony double-diffusion analysis (O. Ouchterlony in: Handbook of Experimental Immunology (D. M. Weir, Ed.), Blackwell Scientific Publications, 1967, pp. 655-706), by crossed immunoelectrophoresis (N. Axelsen et al., supra, Chapters 3 and 4), or by the rocket immunoelectrophoresis (N. Axelsen et al., Chapter 2).

In further aspects, the present invention relates to a detergent composition comprising the mannanase or mannanase preparation of the invention, to a process for machine treatment of fabrics comprising treating fabric during a washing cycle of a machine washing process with a washing solution containing the mannanase or mannanase preparation of the invention, and to cleaning compositions, including laundry, dishwashing, hard surface cleaner, personal cleansing and oral/dental compositions, comprising a mannanase and optionally another enzyme selected among cellulases, amylases, pectin degrading enzymes and xyloglucanases and providing superior cleaning performance, i.e. superior stain removal, dingy cleaning and whiteness maintenance.

Without being bound to this theory, it is believed that the mannanase of the present invention is capable of effectively degrading or hydrolysing any soiling or spots containing galactomannans and, accordingly, of cleaning laundry comprising such soilings or spots.

The cleaning compositions of the invention must contain at least one additional detergent component. The precise nature of these additional components, and levels of incorporation thereof will depend on the physical form of the composition, and the nature of the cleaning operation for which it is to be used.

The cleaning compositions of the present invention preferably further comprises a detergent ingredient selected from a selected surfactant, another enzyme, a builder and/or a bleach system.

The cleaning compositions according to the invention can be liquid, paste, gels, bars, tablets, spray, foam, powder or granular. Granular compositions can also be in “compact” form and the liquid compositions can also be in a “concentrated” form.

The compositions of the invention may for example, be formulated as hand and machine dishwashing compositions, hand and machine laundry detergent compositions including laundry additive compositions and compositions suitable for use in the soaking and/or pretreatment of stained fabrics, rinse added fabric softener compositions, and compositions for use in general household hard surface cleaning operations. Compositions containing such carbohydrases can also be formulated as sanitization products, contact lens cleansers and health and beauty care products such as oral/dental care and persona cleaning compositions.

When formulated as compositions for use in manual dishwashing methods the compositions of the invention preferably contain a surfactant and preferably other detergent compounds selected from organic polymeric compounds, suds enhancing agents, group II metal ions, solvents, hydrotropes and additional enzymes.

When formulated as compositions suitable for use in a laundry machine washing method, the compositions of the invention preferably contain both a surfactant and a builder compound and additionally one or more detergent components preferably selected from organic polymeric compounds, bleaching agents, additional enzymes, suds suppressors, dispersants, lime-soap dispersants, soil suspension and anti-redeposition agents and corrosion inhibitors. Laundry compositions can also contain softening agents, as additional detergent components. Such compositions containing carbohydrase can provide fabric cleaning, stain removal, whiteness maintenance, softening, colour appearance, dye transfer inhibition and sanitization when formulated as laundry detergent compositions.

The compositions of the invention can also be used as detergent additive products in solid or liquid form. Such additive products are intended to supplement or boost the performance of conventional detergent compositions and can be added at any stage of the cleaning process.

If needed the density of the laundry detergent compositions herein ranges from 400 to 1200 g/litre, preferably 500 to 950 g/litre of composition measured at 20° C.

The “compact” form of the compositions herein is best reflected by density and, in terms of composition, by the amount of inorganic filler salt, inorganic filler salts are conventional ingredients of the detergent compositions in powder form; in conventional detergent compositions, the filler salts are present in substantial amounts, typically 17-35% by weight of the total composition. In the compact compositions, the filler salt is present in amounts not exceeding 15% of the total composition, preferably not exceeding 10%, most preferably not exceeding 5% by weight of the composition. The inorganic filler salts, such as meant in the present compositions are selected from the alkali and alkaline-earth-metal salts of sulphates and chlorides. A preferred filler salt is sodium sulphate.

Liquid detergent compositions according to the present invention can also be in a “concentrated form”, in such case, the liquid detergent compositions according the present invention will contain a lower amount of water, compared to conventional liquid detergents. Typically the water content of the concentrated liquid detergent is preferably less than 40%, more preferably less than 30%, most preferably less than 20% by weight of the detergent composition.

The term “pectin degrading enzyme” is intended to encompass arabinanase (EC 3.2.1.99), galactanases (EC 3.2.1.89), polygalacturonase (EC 3.2.1.15) exo-polygalacturonase (EC 3.2.1.67), exo-poly-alpha-galacturonidase (EC 3.2.1.82), pectin lyase (EC 4.2.2.10), pectin esterase (EC 3.2.1.11), pectate lyase (EC 4.2.2.2), exo-polygalacturonate lyase (EC 4.2.2.9) and hemicellulases such as endo-1,3-β-xylosidase (EC 3.2.1.32), xylan-1,4-β-xylosidase (EC 3.2.1.37) and α-L-arabinofuranosidase (EC 3.2.1.55). The pectin degrading enzymes are natural mixtures of the above mentioned enzymatic activities. Pectin enzymes therefore include the pectin methylesterases which hdyrolyse the pectin methyl ester linkages, polygalacturonases which cleave the glycosidic bonds between galacturonic acid molecules, and the pectin transeliminases or lyases which act on the pectic acids to bring about non-hydrolytic cleavage of α-1→4 glycosidic linkages to form unsaturated derivatives of galacturonic acid.

Pectin degrading enzymes are incorporated into the compositions in accordance with the invention preferably at a level of from 0.0001% to 2%, more preferably from 0.0005% to 0.5%, most preferred from 0.001% to 0.1% pure enzyme by weight of the total composition.

Preferred pectin degrading enzymes for specific applications are alkaline pectin degrading enzymes, ie enzymes having an enzymatic activity of at least 10%, preferably at least 25%, more preferably at least 40% of their maximum activity at a pH ranging from 7 to 12. More preferred pectin degrading enzymes are enzymes having their maximum activity at a pH ranging from 7 to 12. Alkaline pectin degrading enzymes are produced by alkalophilic microorganisms e.g. bacterial, fungal and yeast microorganisms such as Bacillus species. Preferred microorganisms are Bacillus firmus, Bacillus circulans, and Bacillus subtilis as described in JP 56131376 and JP 56068393. Alkaline pectin decomposing enzymes include galacturn-1,4-α-galacturonase (EC 3.2.1.67), poly-galacturonase activities (EC 3.2.1.15, pectin esterase (EC 3.1.1.11), pectate lyase (EC 4.2.2.2) and their iso enzymes and they can be produced by the Erwinia species.

Said alkaline pectin enzymes can also be produced by Bacillus species as disclosed in JP 73006557 and Agr. Biol. Chem. (1972), 36 (2) 285-93.

The term xyloglucanase encompasses the family of enzymes described by Vincken and Voragen at Wageningen University [Vincken et al (1994) Plant Physiol., 104, 99-107] and are able to degrade xyloglucans as described in Hayashi et al (1989) Plant. Physiol. Plant Mol. Biol., 40, 139-168. Vincken et al demonstrated the removal of xyloglucan coating from cellulose of the isolated apple cell wall by a xyloglucanase purified from Trichoderma viride (endo-IV-glucanase). This enzyme enhances the enzymatic degradation of cell wall-embedded cellulose and work in synergy with pectic enzymes. Rapidase LIQ+ from Gist-Brocades contains an xyloglucanase activity.

This xyloglucanase is incorporated into the cleaning compositions in accordance with the invention preferably at a level of from 0.0001% to 2%, more preferably from 0.0005% to 0.5%, most preferred from 0.001% to0.1% pure enzyme by weight of the composition.

Preferred xyloglucanases for specific applications are alkaline xyloglucanases, ie enzymes having an enzymatic activity of at least 10%, preferably at lest 25%, more preferably at least 40% of their maximum activity at a pH ranging from 7 to 12. More preferred xyloglucanases are enzymes having their maximum activity at a pH ranging from 7 to 12.

The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Nowadays, it is common practice to modify wild-type enzymes via protein/genetic engineering techniques in order to optimise their performance efficiency in the cleaning compositions of the invention. For example, the variants may be designed such that the compatibility of the enzyme to commonly encountered ingredients of such compositions is increased. Alternatively, the variant may be designed such that the optimal pH, bleach or chelant stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular cleaning application.

In particular, attention should be focused on amino acids sensitive to oxidation in the case of bleach stability and on surface charges for the surfactant compatibility. The isoelectric point of such enzymes may be modified by the substitution of some charged amino acids, e.g. an increase in isoelectric point may help to improve compatibility with anionic surfactants. The stability of the enzymes may be further enhanced by the creation of e.g. additional salt bridges and enforcing metal binding sites to increase chelant stability.

Bleaching agents:

Additional optional detergent ingredients that can be included in the detergent compositions of the present invention include bleaching agents such as PB1, PB4 and percarbonate with a particle size of 400-800 microns. These bleaching agent components can include one or more oxygen bleaching agents and, depending upon the bleaching agent chosen, one or more bleach activators. When present oxygen bleaching compounds will typically be present at levels of from about 1% to about 25%. In general, bleaching compounds are optional added components in non-liquid formulations, e.g. granular detergents.

A bleaching agent component for use herein can be any of the bleaching agents useful for detergent compositions including oxygen bleaches, as well as others known in the art.

A bleaching agent suitable for the present invention can be an activated or non-activated bleaching agent.

One category of oxygen bleaching agent that can be used encompasses percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of meta-chloro perbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid and diperoxydodecanedioic acid. Such bleaching agents are disclosed in U.S. Pat. No. 4,483,781, U.S. 740,446, EP 0 133 354 and U.S. Pat. No. 4,412,934. Highly preferred bleaching agents also include 6-nonylamino-6-oxoperoxycarproic acid as described in U.S. Pat. No. 4,634,551.

Another category of bleaching agents that can be used encompasses the halogen bleaching agents. Examples of hypohalite bleaching agents, for example, include trichloro isocyanuric acid and the sodium and potassium dichloroisocyanurates and N-chloro and N-bromo alkane sulphonamides. Such materials are normally added at 0.5-10% by weight of the finished product, preferably 1-5% by weight.

The hydrogen peroxide releasing agents can be used in combination with bleach activators such as tetra-acetylethylenediamine (TAED), nonanoyloxybenzenesulfonate (NOBS, described in U.S. Pat. No. 4,412,934), 3,5-trimethyl-hexsanoloxybenzenesulfonate (ISONOBS, described in EP 120 591) or pentaacetylglucose (PAG), which are perhydrolyzed to form a peracid as the active bleaching species, leading to improved bleaching effect.

Also suitable activators are acylated citrate esters such as disclosed in European Patent Application No. 91870207.7.

Useful bleaching agents, including peroxyacids and bleaching systems comprising bleach activators and peroxygen bleaching compounds for use in cleaning compositions according to the invention are described in U.S. application Ser. No. 08/136,626.

The hydrogen peroxide may also be present by adding an enzymatic system (i.e. an enzyme and a substrate therefore) which is capable of generation of hydrogen peroxide at the beginning or during the washing and/or rinsing process. Such enzymatic systems are disclosed in European Patent Application EP 0 537 381.

Bleaching agents other than oxygen bleaching agents are also known in the art and can be utilized herein. One type of non-oxygen bleaching agent of particular interest includes photoactivated bleaching agents such as the sulfonated zinc and/or aluminium phthalocyanines. These materials can be deposited upon the substrate during the washing process. Upon irradiation with light, in the presence of oxygen, such as by hanging clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated and, consequently, the substrate is bleached. Preferred zinc phthalocyanine and a photoactivated bleaching process are described in U.S. Pat. No. 4,033,718. Typically, detergent composition will contain about 0.025% to about 1.25%, by weight, of sulfonated zinc phthalocyanine.

Silicones can generally be represented by alkylated polysiloxane materials, while silica is normally used in finely divided forms exemplified by silica aerogels and xerogels and hydrophobic silicas of various types. Theses materials can be incorporated as particulates, in which the suds suppressor is advantageously releasably, incorporated in a water-soluble or water-dispersible, substantially non surface-active detergent impermeable carrier. Alternatively the suds suppressor can be dissolved or dispersed in a liquid carrier and applied by spraying on to one or more of the other components.

Polymers of this type include the polyacrylates and maleic anhydride-acrylic acid copolymers previously mentioned as builders, as well as copolymers of maleic anhydride with ethylene, methylvinyl ether or methacrylic acid, the maleic anhydride constituting at least 20 mole percent of the copolymer. These materials are normally used at levels of from 0.5% to 10% by weight, more preferably form 0.75% to 8%, most preferably from 1% to 6% by weight of the composition.

These are used at levels of from 0.20% to 5% more preferably from 0.25% to 2.5% by weight. These polymers and the previously mentioned homo- or co-polymeric poly-carboxylate salts are valuable for improving whiteness maintenance, fabric ash deposition, and cleaning performance on clay, proteinaceous and oxidizable soils in the presence of transition metal impurities.

Soil release agents useful in compositions of the present invention are conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol and/or propylene glycol units in various arrangements. Examples of such polymers are disclosed in U.S. Pat. Nos. 4,116,885 and 4,711,730 and EP 0 272 033. A particular preferred polymer in accordance with EP 0 272 033 has the formula:

(CH₃(PEG)₄₃)_(0.75)(POH)_(0.25)[T-PO)_(2.8)(T-PEG)_(0.4)]T(POH)_(0.25)((PEG)₄₃CH₃)_(0.75)

where PEG is —(OC₂H₄)O—, PO is (OC₃H₆O) and T is (pOOC₆H₄CO).

Also very useful are modified polyesters as random copolymers of dimethyl terephthalate, dimethyl sulfoisophthalate, ethylene glycol and 1,2-propanediol, the end groups consisting primarily of sulphobenzoate and secondarily of mono esters of ethylene glycol and/or 1,2-propanediol. The target is to obtain a polymer capped at both end by sulphobenzoate groups, “primarily”, in the present context most of said copolymers herein will be endcapped by sulphobenzoate groups. However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or 1,2-propanediol, thereof consist “secondarily” of such species.

The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of 1,2-propanediol, about 10% by weight ethylene glycol, about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about 3.000. The polyesters and their method of preparation are described in detail in EP 311 342.

Softening agents:

Fabric softening agents can also be incorporated into laundry detergent compositions in accordance with the present invention. These agents may be inorganic or organic in type. Inorganic softening agents are exemplified by the smectite clays disclosed in GB-A-1 400898 and U.S. Pat. No. 5,019,292. Organic fabric softening agents include the water insoluble tertiary amines as disclosed in GB-A1 514 276 and EP 0 011 340 and their combination with mono C₁₂-C₁₄ quaternary ammonium salts are disclosed in EP-B 0 026 528 and di-long-chain amides as disclosed in EP- 0 242 919. Other useful organic ingredients of fabric softening systems include high molecular weight polyethylene oxide materials as disclosed in EP 0 299 575 and 0 313 146.

These materials are normally added to the spray dried portion of the composition, although in some instances it may be more convenient to add them as a dry mixed particulate, or spray them as molten liquid on to other solid components of the composition.

Polymeric dye-transfer inhibiting agents:

The detergent compositions according to the present invention may also comprise from 0.001% to 10%, more preferably from 0.01% to 2%, more preferably form 0.05% to 1% by weight of polymeric dye- transfer inhibiting agents. Said polymeric dye-transfer inhibiting agents are normally incorporated into detergent compositions in order to inhibit the transfer of dyes from colored fabrics onto fabrics washed therewith. These polymers have the ability of complexing or adsorbing the fugitive dyes washed out of dyed fabrics before the dyes have the opportunity to become attached to other articles in the wash.

Especially suitable polymeric dye-transfer inhibiting agents are polyamine N-oxide polymers, copolymers of N-vinyl-pyrrolidone and N-vinylimidazole, polyvinylpyrrolidone polymers, polyvinyloxazolidones and polyvinylimidazoles or mixtures thereof.

Addition of such polymers also enhances the performance of the enzymes according the invention.

Use in the Paper Pulp Industry

Further, it is contemplated that the mannanase of the present invention is useful in chlorine-free bleaching processes for paper pulp (chemical pumps, semichemical pumps, mechanical pulps or kraft pulps) in order to increase the brightness thereof, thus decreasing or eliminating the need for hydrogen peroxide in the bleaching process.

Use in the Textile and Cellulosic Fiber Processing Industries

The mannanase of the present invention can be used in combination with other carbohydrate degrading enzymes (for instance xyloglucanase, xylanase, various pectinases) for preparation of fibers or for cleaning of fibers in combination with detergents.

In the present context, the term “cellulosic material” is intended to mean fibers, sewn and unsewn fabrics, including knits, wovens, denims, yarns, and toweling, made from cotton, cotton blends or natural or manmade cellulosics (e.g. originating from xylan-containing cellulose fibers such as from wood pulp) or blends thereof. Examples of blends are blends of cotton or rayon/viscose with one or more companion material such as wool, synthetic fibers (e.g. polyamide fibers, acrylic fibers, polyester fibers, polyvinyl alcohol fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polyurethane fibers, polyurea fibers, aramid fibers), and cellulose-containing fibers (e.g. rayon/viscose, ramie, hemp, flax-linen, jute, cellulose acetate fibers, lyocell).

The processing of cellulosic material for the textile industry, as for example cotton fiber, into a material ready for garment manufacture involves several steps: spinning of the fiber into a yarn; construction of woven or knit fabric from the yarn and subsequent preparation, dyeing and finishing operations. Woven goods are constructed by weaving a filling yarn between a series of warp yarns; the yarns could be two different types.

Desizing: polymeric size like e.g. mannan, starch, CMC or PVA is added before weaving in order to increase the warp speed; This material must be removed before further processing. The enzyme of the invention is useful for removal of mannan containing size.

Degradation of Thickeners

Galactomannans such as guar gum and locust bean gum are widely used as thickening agents e.g. in food and print paste for textile printing such as prints on T-shirts. The enzyme or enzyme preparation according to the invention can be used for reducing the viscosity of eg residual food in processing equipment and thereby facilitate cleaning after processing. Further, it is contemplated that the enzyme or enzyme preparation is useful for reducing viscosity of print paste, thereby facilitating wash out of surplus print paste after textile printins.

Degradation or Modification of Plant Material

The enzyme or enzyme preparation according to the invention is preferably used as an agent for degradation or modification of mannan, galactomannan, glucomannan or galactoglucomannan containing material originating from plants. Examples of such material is guar gum and locust bean gum.

The mannanase of the invention may be used in modifying the physical-chemical properties of plant derived material such as the viscosity. For instance, the mannanase may be used to reduce the viscosity of feed or food which contain mannan and to promote processing of viscous mannan containing material.

Coffee Extraction

The enzymes or enzyme preparation of the invention may also be used for hydrolysing galactomannans present in a liquid coffee extract, preferably in order to inhibit gel formation during freeze drying of the (instant) coffee. Preferably, the mannanase of the invention is immobilized in order to reduce enzyme consumption and avoid contamination of the coffee. This use is further disclosed in EP-A-676 145.

Use in the Fracturing of a Subterranean Formation (Oil Drilling)

Further, it is contemplated that the enzyme of the present invention is useful as an enzyme breaker as disclosed in U.S. Pat. Nos. 5,806,597, 5,562,160, 5,201,370 and 5,067,566 to BJ Services Company (Houston, Tex., U.S.A.), all of which are hereby incorporated by reference.

Accordingly, the mannanase of the present invention is useful in a method of fracturing a subterranean formation in a well bore in which a gellable fracturing fluid is first formed by blending together an aqueous fluid, a hydratable polymer, a suitable cross-linking agent for cross-linking the hydratable polymer to form a polymer gel and an enzyme breaker, ie the enzyme of the invention. The cross-linked polymer gel is pumped into the well bore under sufficient pressure to fracture the surrounding formation. The enzyme breaker is allowed to degrade the cross-linked polymer with time to reduce the viscosity of the fluid so that the fluid can be pumped from the formation back to the well surface.

The enzyme breaker may be an ingredient of a fracturing fluid or a breaker-crosslinker-polymer complex which further comprises a hydratable polymer and a crosslinking agent. The fracturing fluid or complex may be a gel or may be gellable. The complex is useful in a method for using the complex in a fracturing fluid to fracture a subterranean formation that surrounds a well bore by pumping the fluid to a desired location within the well bore under sufficient pressure to fracture the surrounding subterranean formation. The complex may be maintained in a substantially non-reactive state by maintaining specific conditions of pH and temperature, until a time at which the fluid is in place in the well bore and the desired fracture is completed. Once the fracture is completed, the specific conditions at which the complex is inactive are no longer maintained. When the conditions change sufficiently, the complex becomes active and the breaker begins to catalyze polymer degradation causing the fracturing fluid to become sufficiently fluid to be pumped from the subterranean formation to the well surface.

General Molecular Biology Methods

Unless otherwise stated all the DNA manipulations and transformations were performed using standard methods of molecular biology (Sambrook et al. (1989) Molecular cloning: A laboratory manual, Cold Spring Harbor lab., Cold Spring Harbor, N.Y.; Ausubel, F. M. et al. (eds.) “Current protocols in Molecular Biology”. John Wiley and Sons, 1995; Harwood, C. R., and Cutting, S. M. (eds.) “Molecular Biological Methods for Bacillus”. John Wiley and Sons, 1990).

Enzymes for DNA manipulations were used according to the manufacturer's instructions (e.g. restriction endonucleases, ligases etc. are obtainable from New England Biolabs, Inc.).

Plasmids

pSJ1678: (see International Patent Application published as WO 94/19454).

pBK-CMV (Stratagene inc., La Jolla Calif.)

pMOL944. This plasmid is a pUB110 derivative essentially containing elements making the plasmid propagatable in Bacillus subtilis, kanamycin resistance gene and having a strong promoter and signal peptide cloned from the amyL of B.licheniformis ATCC14580. The signal peptide contains a SacII site making it convenient to clone the DNA encoding the mature part of a protein in-fusion with the signal peptide. This results in the expression of a Pre-protein which is directed towards the exterior of the cell.

The plasmid was constructed by means of ordinary genetic engineering and is briefly described in the following.

Construction of pMOL944

The pUB110 plasmid (McKenzie, T. et al., 1986, Plasmid 15: 93-103) was digested with the unique restriction enzymes NciI. A PCR fragment amplified from the amyL promoter encoded on the plasmid pDN1981 (P. L. Jørgensen et al.,1990, Gene, 96, p.37-41.) was digested with NciI and inserted in the NciI digested pUB110 to give the plasmid pSJ2624.

The two PCR primers used have the following sequences:

#LWN5494 5′-GTCGCCGGGGCGGCCGCTATCAATTGGTAACTGTATCTCAGC-3′ (SEQ ID NO: 35)

#LWN5495 5′-GTCGCCCGGGAGCTCTGATCAGGTACCAAGCTTGTCGACCTGCAGAA TGAGGCAGCAAGAAGAT-3′ (SEQ ID NO: 36)

The primer #LWN5494 inserts a NotI site in the plasmid.

The plasmid pSJ2624 was then digested with SacI and NotI and a new PCR fragment amplified on amyL promoter encoded on the pDN1981 was digested with SacI and NotI and this DNA fragment was inserted in the SacI-NotI digested pSJ2624 to give the plasmid pSJ2670.

This cloning replaces the first amyL promoter cloning with the same promoter but in the opposite direction. The two primers used for PCR amplification have the following sequences:

#LWN5938 5′-GTCGGCGGCCGCTGATCACGTACCAAGCTTGTCGACCTGCAGAATG AGGCAGCAAGAAGAT-3′ (SEQ ID NO: 37)

#LWN5939 5′-GTCGGAGCTCTATCAATTGGTAACTGTATCTCAGC-3′ (SEQ ID NO: 38)

The plasmid pSJ2670 was digested with the restriction enzymes PstI and BcII and a PCR fragment amplified from a cloned DNA sequence encoding the alkaline amylase SP722 (Patent # WO 9526397-A1) was digested with PstI and BcII and inserted to give the plasmid pMOL944. The two primers used for PCR amplification have the following sequence:

#LWN7864 5′-AACAGCTGATCACGACTGATCTTTTAGCTTGGCAC-3′ (SEQ ID NO: 39)

#LWN7901 5′-AACTGCAGCCGCGGCACATCATAATGGGACAAATGGG-3′ (SEQ ID NO: 40)

The primer #LWN7901 inserts a SacII site in the plasmid.

Cultivation of Donor strains and Isolation of Genomic DNA

The relevant strain of Bacillus, eg Bacillus sp. I633, was grown in TY with pH adjusted to approximately pH 9.7 by the addition of 50 ml of 1M Sodium-Sesquicarbonat per 500 ml TY. After 24 hours incubation at 30° C. and 300 rpm, the cells were harvested, and genomic DNA was isolated by the method described by Pitcher et al. [Pitcher, D. G., Saunders, N. A., Owen, R. J; Rapid extraction of bacterial genomic DNA with guanidium thiocyanate; Lett Appl Microbiol 1989 8 151-156].

EXAMPLE 1 Mannanase Derived from Bacillus sp (I633)

Construction of a genomic library from Bacillus sp. I633 in the lambdaZAPExpress vector

Genomic DNA of Bacillus sp. I633 was partially digested with restriction enzyme Sau3A, and size-fractionated by electrophoresis on a 0.7% agarose gel (SeaKem agarose, FMC, USA). Fragments between 1.5 and 10 kb in size were isolated and concentrated to a DNA band by running the DNA fragments backwards on a 1.5% agarose gel followed by the extraction of the fragments from the agarose gel slice using the Qiaquick gel extraction kit according to the manufacturer's instructions (Qiagen Inc., USA). To construct a genomic library, ca. 100 ng of purified, fractionated DNA from above was ligated with 1 ug of BamHI-cleaved, dephosphorylated lambdaZAPexpress vector arms (Stratagene, La Jolla Calif., USA) for 24 hours at +4° C. according to the manufacturer's instructions. A 3-ul aliquot of the ligation mixture was packaged directly using the GigaPackIII Gold packaging extract (Stratagene, USA) according to the manufacturers instructions (Stratagene). The genomic lambdaZAPExpress phage library was titered using the E. coli XL1-Blue MRF-strain from Stratagene (La Jolla, USA). The unamplified genomic library comprised of 3×10⁷ plaque-forming units (pfu) with a vector background of less than 1%.

Screening for beta-mannanase clones by functional expression in lambdaZAPExpress

Approximately 5000 plaque-forming units (pfu) from the genomic library were plated on NZY-agar plates containing 0.1% AZCL-galactomannan (MegaZyme, Australia, cat. no. I-AZGMA), using E. coli XL1-Blue MRF′ (Stratagene, USA) as a host, followed by incubation of the plates at 37° C. for 24 hours. Mannanase-positive lambda clones were identified by the formation of blue hydrolysis halos around the positive phage clones. These were recovered from the screening plates by coring the TOP-agar slices containing the plaques of interest into 500 ul of SM buffer and 20 ul of chloroform. The mannanase-positive lambdaZAPExpress clones were plaque-purified by plating an aliquot of the cored phage stock on NZY plates containing 0.1% AZCL-galactomannan as above. Single, mannanase-positive lambda clones were cored into 500 ul of SM buffer and 20 ul of chloroform, and purified by one more plating round as described above.

Single-clone in vivo excision of the phagemids from the mannanase-positive lambdaZAPExpress clones

E. coli XL1-Blue cells (Stratagene, La Jolla, Calif.) were prepared and resuspended in 10 mM MgSO4 as recommended by Stratagene (La Jolla, USA). 250-ul aliquots of the pure phage stocks from the mannase-positive clones were combined in Falcon 2059 tubes with 200 uls of XL1-Blue MRF′ cells (OD600=1.0) and >10⁶ pfus/ml of the ExAssist M13 helper phage (Stratagene), and the mixtures were incubated at 37° C. for 15 minutes. Three mls of NZY broth was added to each tube and the tubes were incubated at 37 C for 2.5 hours. The tubes were heated at 65° C. for 20 minutes to kill the E. coli cells and bacteriophage lambda; the phagemids being resistant to heating. The tubes were spun at 3000 rpm for 15 minutes to remove cellular debris and the supernatants were decanted into clean Falcon 2059 tubes. Aliquots of the supernatants containing the excised single-stranded phagemids were used to infect 200 uls of E. coli XLOLR cells (Stratagene, OD600=1.0 in 10 mM MgSO4) by incubation at 37° C. for 15 minutes. 350 uls of NZY broth was added to the cells and the tubes were incubated for 45 min at 37° C. Aliquots of the cells were plated onto LB kanamycin agar plates and incubated for 24 hours at 37° C. Five excised single colonies were re-streaked onto LB kanamycin agar plates containing 0.1% AZCL-galactomannan (MegaZyme, Australia). The mannanase-positive phagemid clones were characterized by the formation of blue hydrolysis halos around the positive colonies. These were further analysed by restriction enzyme digests of the isolated phagemid DNA (QiaSpin kit, Qiagen, USA) with EcoRI, PstI, EcoRI-PstI, and HindIII followed by agarose gel electrophoresis.

Nucleotide sequence analysis

The nucleotide sequence of the genomic beta-1,4-mannanase clone pBXM3 was determined from both strands by the dideoxy chain-termination method (Sanger, F., Nicklen, S., and Coulson, A. R. (1977) Proc. Natl. Acad. Sci. U. S. A. 74, 5463-5467) using 500 ng of Qiagen-purified template (Qiagen, USA), the Taq deoxy-terminal cycle sequencing kit (Perkin-Elmer, USA), fluorescent labeled terminators and 5 pmol of either pBK-CMV polylinker primers (Stratagene, USA) or synthetic oligonucleotide primers. Analysis of the sequence data was performed according to Devereux et al., 1984 (Devereux, J., Haeberli, P., and Smithies, O. (1984) Nucleic Acids Res. 12, 387-395).

Chromosomal DNA isolated from Bacillus sp. I633 as described above was used as template in a PCR reaction using Amplitaq DNA Polymerase (Perkin Elmer) according to manufacturers instructions. The PCR reaction was set up in PCR buffer (10 mM Tris-HCl, pH 8.3, 50 mM KCl, 1.5 mM MgCl₂, 0.01% (w/v) gelatin) containing 200 μm of each dNTP, 2.5 units of AmpliTaq polymerase (Perkin-Elmer, Cetus, USA) and 100 pmol of each primer.

One incubation at 94° C. for 1 min followed by thirty cycles of PCR performed using a cycle profile of denaturation at 94° C. for 30 sec, annealing at 60° C. for 1 min, and extension at 72° C. for 2 min. Five-μl aliquots of the amplification product was analysed by electrophoresis in 0.7% agarose gels (NuSieve, FMC). The appearance of a DNA fragment size 1.0 kb indicated proper amplification of the gene segment.

Subcloning of PCR fragment:

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIAquick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified DNA was eluted in 50 μm of 10 mM Tris-HCl, pH 8.5. 5 μg of pMOL944 and twentyfive-μl of the purified PCR fragment was digested with SacII and NotI, electrophoresed in 0.8% low gelling temperature agarose (SeaPlaque GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIAquick Gel extraction Kit (Qiagen, USA) according to the manufacturer's instructions. The isolated PCR DNA fragment was then ligated to the SacII-NotI digested and purified pMOL944. The ligation was performed overnight at 16° C. using 0.5 μg of each DNA fragment, 1 U of T4 DNA ligase and T4 ligase buffer (Boehringer Mannheim, Germany).

The ligation mixture was used to transform competent B.subtilis PL2306. The transformed cells were plated onto LBPG-10 μg/ml of Kanamycin-agar plates. After 18 hours incubation at 37° C. colonies were seen on plates. Several clones were analyzed by isolating plasmid DNA from overnight culture broth.

One such positive clone was restreaked several times on agar plates as used above, this clone was called MB748. The clone MB748 was grown overnight in TY-10 μg/ml Kanamycin at 37° C., and next day 1 ml of cells were used to isolate plasmid from the cells using the Qiaprep Spin Plasmid Miniprep Kit #27106 according to the manufacturers recommendations for B. subtilis plasmid preparations. This DNA was DNA sequenced and revealed the DNA sequence corresponding to the mature part of the mannanase (corresponding to positions 94-990 of SEQ ID NO: 1 and positions 32-330 of SEQ ID NO: 2) with introduced stop codon replacing the amino acid residue no 331 corresponding to the base pair positions 1201-1203 in SEQ ID NO: 1.

Subcloning of PCR fragment:

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIAquick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified DNA was eluted in 50 μl of 10 mM Tris-HCl, pH 8.5. 5 μg of pMOL944 and twentyfive-μl of the purified PCR fragment was digested with SacII and NotI, electrophoreses in 0.8% low gelling temperature agarose (SeaPlague GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIAquick Gel extraction Kit (Qiagen, USA) according to the manufacturer's instructions.

This DNA was DNA sequenced and revealed the DNA sequence corresponding to the mature part of the mannanase position 317-1693 in SEQ ID NO. 1 and 33-490 in the SEQ ID NO. 2.

The clone MB643 was grown in 25×200 ml BPX media with 10 μg/ml of Kanamycin in 500 ml two baffled shakeflasks for 5 days at 37° C. at 300 rpm.

The DNA sequence encoding the C-terminal domain of unknown function from amino acid residue no. 341 to amino acid residue no. 490 shows high homology to a domain denoted X18 from a known mannanase. This X18 is found in EMBL entry AB007123 from: Yoshida S., Sako Y., Uchida A.: “Cloning, sequence analysis, and expression in Escherichia coli of a gene coding for an enzyme from Bacillus circulans K-1 that degrades guar gum” in Biosci. Biotechnol. Biochem. 62:514-520 (1998). This gene codes for the signal peptide (aa 1-34), the catalytic core of a family 5 mannanase (aa 35-335), a linker (aa 336-362) and finally the X18 domain of unknown function (aa 363-516).

This X18 domain is also found in Bacillus subtilis beta-mannanase Swiss protein database entry P55278 which discloses a gene coding for a signal peptide (aa 1-26), a catalytic core family 26 mannanase (aa 27-360) and this X18 protein domain of unknown function (aa 361-513); (Cloning and sequencing of beta-mannanase gene from Bacillus subtilis NM-39, Mendoza NS; Arai M; Sugiomto K; Ueda M; Kawaguchi T; Joson LM, Phillippines.

EXAMPLE 2 Expression, Purification and Characterisation of Mannanase from Bacillus sp. I633

The clone MB748 obtained as described in Example 1 and under Materials and Methods was grown in 25×200 ml BPX media with 10 μg/ml of Kanamycin in 500 ml two baffled shakeflasks for 5 days at 37° C. at 300 rpm.

4500 ml of the shake flask culture fluid of the clone MB748 was collected and pH was adjusted to 5.6. 100 ml of cationic agent (10% C521) and 180 ml of anionic agent (A130) was added during agitation for flocculation. The flocculated material was separated by centrifugation using a Sorval RC 3B centrifuge at 9000 rpm for 20 min at 6° C. The supernatant was clarified using Whatman glass filters GF/D and C and finally concentrated on a filtron with a cut off of 10 kDa.

700 ml of this concentrate was adjusted to pH 7.5 using sodium hydroxide. The clear solution was applied to anion-exchange chromatography using a 1000 ml Q-Sepharose column equilibrated with 50 mmol Tris pH 7.5. The mannanase activity bound was eluted in 1100 ml using a sodium chloride gradient. This was concentrated to 440 ml using a Filtron membrane. For obtaining highly pure mannanase the concentrate was passed over a Superdex 200 column equilibrated with 0.1M sodium acetate, pH 6.0.

The pure enzyme gave a single band in SDS-PAGE with a molecular weight of 34 kDa.

Steady state kinetic using locust bean gum:

The assay was carried out using different amounts of the substrate locust bean gum, incubating for 20 min at 40° C. at pH 10 in 1.0 M Glycine buffer, followed by the determination of formation of reducing sugars. Glucose was used as standard for calculation of micromole formation of reducing sugar during steady state.

The following data was obtained for the highly purified mannanase of the invention:

KCat of 467 per sec with a standard deviation of 13;

kM of 0.7 with a standard deviation of 0.07.

The computer program grafit by Leatherbarrow from Erithacus Software U.K. was used for calculations. Reducing sugar was determined using the PHBAH method (Lever, M. (1972), A new reaction for colormetric determination of carbohydrates. Anal. Biochem. 47, 273-279.)

The following N-terminal sequence of the purified protein was determined: ANSGFYVSGTTLYDANG (amino acids 32-48 of SEQ ID NO:2).

Stability: The mannanase was fully stable between pH 6.0 and 11 after incubation for 2 days at room temperature. The enzyme precipitated at low pH.

The pH activity profile shows that the enzyme is more than 60% active between pH 7.5 and pH 10.

Temperature optimum was found to be 50° C. at pH 10.

DSC differential scanning calometry gave 66° C. as melting point at pH 6.0 in sodium acetate buffer indicating that this mannanase enzyme is thermostable.

Immunological properties: Rabbit polyclonal monospecific serum was raised against the highly purified cloned mannanase using conventional techniques at the Danish company DAKO. The serum formed a nice single precipitate in agarose gels with the crude non purified mannanase of the invention.

EXAMPLE 3 Use of the Enzyme of Example 2 in Detergents

Using commercial detergents instead of buffer and incubation for 20 minutes at 40° C. with 0.2% AZCL-Galactomannan (Megazyme, Australia) from carob degree as described above followed by determination of the formation of blue color, the enzyme obtained as described in example 2 was active in European powder detergent Ariel Futur with 60% relative activity, European liquid detergent Ariel Futur with 80% relative activity, in US Tide powder with 45% relative activity and in US Tide liquid detergent with 37% relative activity to the activity measured in Glycine buffer. In these tests, the detergent concentration was as recommended on the commercial detergent packages and the wash water was tap water having 18 degrees German hardness under European (Ariel Futur) conditions and 9 degree under US conditions (US Tide).

A DNA sample encoding the CBD was used as template in a PCR and the CBD was cloned in an apprpopriate plasmid pMB993 based on the pMOL944 vector.

The pMB993 vector contains the CipB CBD with a peptide linker preceeding the CBD. The linker consists of the following peptides sequence ASPEPTPEPT (SEQ ID NO: 49) and is directly followed by the CipB CBD. The AS amino acids are derived from the DNA sequence that constitutes the Restriction Endonuclease site NheI, which in the following is used to clone the mannanase of the invention.

Restriction sites NheI and SacII are underlined. Chromosomal DNA isolated from Bacillus sp. I633 as described above was used as template in a PCR reaction using Amplitaq DNA Polymerase (Perkin Elmer) according to manufacturers instructions. The PCR reaction was set up in PCR buffer (10 mM Tris-HCl, pH 8.3, 50 mM KCl, 1.5 mM MgCl₂, 0.01% (w/v) gelatin) containing 200 μM of each dNTP, 2.5 units of AmpliTaq polymerase (Perkin-Elmer, Cetus, USA) and 100 pmol of each primer.

The PCR reactions was performed using a DNA thermal cycler (Landgraf, Germany). One incubation at 94° C. for 1 min followed by thirty cycles of PCR performed using a cycle profile of denaturation at 94° C. for 30 sec, annealing at 60° C. for 1 min, and extension at 72° C. for 2 min. Five-μl aliquots of the amplification product was analysed by electrophoresis in 0.7% agarose gels (NuSieve, FMC). The appearance of a DNA fragment size 0.9 kb indicated proper amplification of the gene segment.

Subcloning of PCR fragment:

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIAquick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified DNA was eluted in 50 μl of 10 mM Tris-HCl, pH 8.5. 5 μg of pMB993 and twentyfive-μl of the purified PCR fragment was digested with SacII and NheI, electrophoresed in 0.7% low gelling temperature agarose (SeaPlaque GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIAquick Gel extraction Kit (Qiagen, USA) according to the manufacturer's instructions. The isolated PCR DNA fragment was then ligated to the SacII-NheI digested and purified pMB993. The ligation was performed overnight at 16° C. using 0.5 μg of each DNA fragment, 1 U of T4 DNA ligase and T4 ligase buffer (Boehringer Mannheim, Germany).

The ligation mixture was used to transform competent B. subtilis PL2306. The transformed cells were plated onto LBPG-10 μg/ml of Kanamycin-agar plates. After 18 hours incubation at 37° C. colonies were seen on plates. Several clones were analyzed by isolating plasmid DNA from overnight culture broth.

One such positive clone was restreaked several times on agar plates as used above, this clone was called MB1014. The clone MB1014 was grown overnight in TY-10 μg/ml Kanamycin at 37° C., and next day 1 ml of cells were used to isolate plasmid from the cells using the Qiaprep Spin Plasmid Miniprep Kit #27106 according to the manufacturers recommendations for B. subtilis plasmid preparations. This DNA was DNA sequenced and revealed the DNA sequence corresponding to the mature part of the Mannanase-linker-cbd as represented in SEQ ID NO:3 and in the appended protein sequence SEQ ID NO: 4.

Thus the final construction contains the following expression relevant elements: (amyL-promoter)-(amyL-signalpeptide)-mannanase-linker-CBD.

Expression and Detection of Mannanase-CBD Fusion Protein

MB1014 was incubated for 20 hours in TY-medium at 37° C. and 250 rpm. 1 ml of cell-free supernatant was mixed with 200 μl of 10% Avicel (Merck, Darmstadt, Germany) in Millipore H2O. The mixture was left for ½ hour incubation at 0° C. After this binding of BXM2-Linker-CBD fusion protein to Avicel the Avicel with bound protein was spun 5 min at 5000 g. The pellet was resuspended in 100 μl of SDS-page buffer, boiled at 95° C. for 5 min, spun at 5000 g for 5 min and 25 μl was loaded on a 4-20% Laemmli Tris-Glycine, SDS-PAGE NOVEX gel (Novex, USA). The samples were electrophoresed in a Xcell™ Min-Cell (NOVEX, USA) as recommended by the manufacturer, all subsequent handling of gels including staining with comassi, destaining and drying were performed as described by the manufacturer.

The appearance of a protein band of approx. 53 kDa, verified the expression in B. subtilis of the full length Mannanase-Linker-CBD fusion encoded on the plasmid pMB1014.

Five-μl aliquots of the amplification product was analysed by electrophoresis in 0.7% agarose gels (NuSieve, FMC). The appearance of a DNA fragment size 1.4 kb indicated proper amplification of the gene segment.

Subcloning of PCR fragment

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIAquick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified DNA was eluted in 50 μl of 10 mM Tris-HCl, pH 8.5. 5 μg of pMOL944 and twentyfive-μl of the purified PCR fragment was digested with SacII and NotI, electrophoresed in 0.8% low gelling temperature agarose (SeaPlaque GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIAquick Gel extraction kit (Qiagen, USA) according to the manufacturer's instructions.

This DNA was DNA sequenced and revealed the DNA sequence corresponding to the mature part of the mannanase, i.e. positions 94-1404 of the appended SEQ ID NO:7. The derived mature protein is shown in SEQ ID NO:8. It will appear that the 3′ end of the mannanse encoded by the sequence of SEQ ID NO:5 was changed to the one shown in SEQ ID NO:7 due to the design of the lower primer used in the PCR. The resulting amino acid sequence is shown in SEQ ID NO:8 and it is apparent that the C terminus of the SEQ ID NO:6 (SHHVREIGVQFSAADNSSGQTALYVDNVTLR) is changed to the C terminus of SEQ ID NO:8 (IIMLGK).

EXAMPLE 6 Expression, Purification and Characterisation of Mannanase from Bacillus agaradhaerens

The clone MB 594 obtained as described in example 5 was grown in 25×200 ml BPX media with 10 μg/ml of Kanamycin in 500 ml two baffled shakeflasks for 5 days at 37° C. at 300 rpm.

6500 ml of the shake flask culture fluid of the clone MB 594 (batch #9813) was collected and pH adjusted to 5.5. 146 ml of cationic agent (C521) and 292 ml of anionic agent (A130) was added during agitation for flocculation. The flocculated material was separated by centrifugation using a Sorval RC 3B centrifuge at 9000 rpm for 20 min at 6° C. The supernatant was clarified using Whatman glass filters GF/D and C and finally concentrated on a filtron with a cut off of 10 kDa.

750 ml of this concentrate was adjusted to pH 7.5 using sodium hydroxide. The clear solution was applied to anion-exchange chromatography using a 900 ml Q-Sepharose column equilibrated with 50 mmol Tris pH 7.5. The mannanase activity bound was eluted using a sodium chloride gradient.

The pure enzyme gave a single band in SDS-PAGE with a molecular weight of 38 kDa.

The amino acid sequence of the mannanase enzyme, i.e. the translated DNA sequence, is shown in SEQ ID No.6.

Determination of kinetic constants:

Substrate: Locust bean gum (carob) and reducing sugar analysis (PHBAH). Locust bean gum from Sigma (G-0753).

Kinetic determination using different concentrations of locust bean gum and incubation for 20 min at 40° C. at pH 10 gave

Kcat: 467 per sec.

K_(m): 0.08 gram per l

MW: 38 kDa

pI (isoelectric point): 4.2

The temperature optimum of the mannanase was found to be 60° C.

The pH activity profile showed maximum activity between pH 8 and 10.

DSC differential scanning calometry gives 77° C. as melting point at pH 7.5 in Tris buffer indicating that this enzyme is very termostable.

Detergent compatibility using 0.2% AZCL-Galactomannan from carob as substrate and incubation as described above at 40° C. shows excellent compability with conventional liquid detergents and good compability with conventional powder detergents.

EXAMPLE 7 Use of the Enzyme of the Invention in Detergents

The purified enzyme obtained as described in example 6 (batch #9813) showed improved cleaning performance when tested at a level of 1 ppm in a miniwash test using a conventional commercial liquid detergent. The test was carried out under conventional North American wash conditions.

EXAMPLE 8 Mannanase derived from Bacillus sp. AAI12

Construction of a genomic library from Bacillus sp. AAI12

Genomic DNA of Bacillus sp. was partially digested with restriction enzyme Sau3A, and size-fractionated by electrophoresis on a 0.7% agarose gel (SeaKem agarose, FMC, USA). Fragments between 1.5 and 10 kb in size were isolated and concentrated to a DNA band by running the DNA fragments backwards on a 1.5% agarose gel followed by extraction of the fragments from the agarose gel slice using the Qiaquick gel extraction kit according to the manufacturer's instructions (Qiagen Inc., USA). To construct a genomic library, ca. 100 ng of purified, fractionated DNA from above was ligated with 1 ug of BamHI-cleaved, dephosphorylated lambdaZAPexpress vector arms (Stratagene, La Jolla Calif., USA) for 24 hours at +4° C. according to the manufacturer's instructions. A 3-ul aliquot of the ligation mixture was packaged directly using the GigaPackIII Gold packaging extract (Stratagene, USA) according to the manufactures instructions (Stratagene). The genomic lambdaZAPExpress phage library was titered using the E. coli XL1-Blue MRF-strain from Stratagene (La Jolla, USA). The unamplified genomic library comprised of 7.8×107 plaque-forming units (pfu) with a vector background of less than 1%.

Screening for beta-mannanase clones by functional expression in lambdaZAPExpress

Approximately 5000 plaque-forming units (pfu) from the genomic library were plated on NZY-agar plates containing 0.1% AZCL-galactomannan (MegaZyme, Australia, cat. no. I-AZGMA), using E. coli XL1-Blue MRF′ (Stratagene, USA) as a host, followed by incubation of the plates at 37° C. for 24 hours. Mannanase-positive lambda clones were identified by the formation of blue hydrolysis halos around the positive phage clones. These were recovered from the screening plates by coring the TOP-agar slices containing the plaques of interest into 500 ul of SM buffer and 20 ul of chloroform. The mannanase-positive lambdaZAPExpress clones were plaque-purified by plating an aliquot of the cored phage stock on NZY plates containing 0.1% AZCL-galactomannan as above. Single, mannanase-positive lambda clones were cored into 500 ul of SM buffer and 20 ul of chloroform, and purified by one more plating round as described above.

Single-clone in vivo excision of the phagemids from the mannanase-positive lambdaZAPExpress clones

E. coli XL1-Blue cells (Stratagene, La Jolla Calif.) were prepared and resuspended in 10 mM MgSO4 as recommended by Stratagene (La Jolla, USA). 250-ul aliquots of the pure phage stocks from the mannase-positive clones were combined in Falcon 2059 tubes with 200 uls of XL1-Blue MRF′ cells (OD600=1.0) and >106 pfus/ml of the ExAssist M13 helper phage (Stratagene), and the mixtures were incubated at 37 C for 15 minutes. Three mls of NZY broth was added to each tube and the tubes were incubated at 37 C for 2.5 hours. The tubes were heated at 65 C for 20 minutes to kill the E. coli cells and bacteriophage lambda; the phagemids being resistant to heating. The tubes were spun at 3000 rpm for 15 minutes to remove cellular debris and the supernatants were decanted into clean Falcon 2059 tubes. Aliquots of the supernatants containing the excised single-stranded phagemids were used to infect 200 uls of E. coli XLOLR cells (Stratagene, OD600=1.0 in 10 mM MgSO4) by incubation at 37° C. for 15 minutes. 350 uls of NZY broth was added to the cells and the tubes were incubated for 45 min at 37° C. Aliquots of the cells were plated onto LB kanamycin agar plates and incubated for 24 hours at 37° C. Five excised single colonies were re-streaked onto LB kanamycin agar plates containing 0.1% AZCL-galactomannan (MegaZyme, Australia). The mannanase-positive phagemid clones were characterized by the formation of blue hydrolysis halos around the positive colonies. These were further analysed by restriction enzyme digests of the isolated plagemid DNA (QiaSpin kit, Qiagen, USA) with EcoRI, PstI, EcoRI-PstI, and HindIII followed by agarose gel electrophoresis.

The nucleotide sequence of the genomic beta-1,4-mannanase clone pBXM1 was determined from both strands by the dideoxy chain-termination method (Sanger, F., Nicklen, S., and Coulson, A. R. (1977) Proc. Natl. Acad. Sci. U. S. A. 74, 5463-5467) using 500 ng of Qiagen-purified template (Qiagen, USA), the Taq deoxy-terminal cycle sequencing kit (Perkin-Elmer, USA), fluorescent labeled terminators and 5 pmol of either pBK-CMV polylinker primers (Stratagene, USA) or synthetic oligonucleotide primers. Analysis of the sequence data was performed according to Devereux et al. 1984 (Devereux, J., Haeberli, P., and Smithies, O. (1984) Nucleic Acids Res. 12, 387-395).

Subcloning of PCR fragment

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIAquick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified DNA was eluted in 50 μl of 10 mM Tris-HCl, pH 8.5. 5 μg of pMOL944 and twentyfive-μl of the purified PCR fragment was digested with SacII and NotI, electrophoresed in 0.8% low gelling temperature agarose (SeaPlaque GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIAquick Gel extraction Kit (Qiagen, USA) according to the manufacturer's instructions.

This DNA was DNA sequenced and revealed the DNA sequence corresponding to the mature part of the mannanase in the SEQ ID NO. 9.

Expression, Purification and Characterisation of Mannanase from Bacillus sp. AAI 12

The clone MB747 obtained as described above was grown in 25×200 ml BPX media with 10 μg/ml of Kanamycin in 500 ml two baffled shakeflasks for 5 days at 37° C. at 300 rpm.

Chromosomal DNA isolated from Bacillus halodurans as described above was used as template in a PCR reaction using Amplitaq DNA Polymerase (Perkin Elmer) according to manufacturers instructions. The PCR reaction was set up in PCR buffer (10 mM Tris-HCl, pH 8.3, 50 mM KCl, 1.5 mM MgCl2, 0.01% (w/v) gelatin) containing 200 μM of each dNTP, 2.5 units of AmpliTaq polymerase (Perkin-Elmer, Cetus, USA) and 100 pmol of each primer.

The PCR reactions was performed using a DNA thermal cycler (Landgraf, Germany). One incubation at 94° C. for 1 min followed by thirty cycles of PCR performed using a cycle profile of denaturation at 94° C. for 30 sec, an-nea-ling at 60° C. for 1 min, and extension at 72° C. for 2 min. Five-μl aliquots of the ampli-fication product was analysed by electrophoresis in 0.7% agarose gels (NuSieve, FMC). The appearance of a DNA fragment size 0.9 kb indicated proper amplification of the gene segment.

Subcloning of PCR fragment:

Fortyfive-μl aliquots of the PCR products generated as described above were purified using QIA-quick PCR purification kit (Qiagen, USA) according to the manufacturer's instructions. The purified D-NA was eluted in 50 μl of 10 mM Tris-HCl, pH 8.5.

5 μg of pMOL944 and twentyfive-μl of the purified PCR fragment was digested with SacII and NotI, electrophoresed in 0.8% low gelling temperature agarose (SeaPla-que GTG, FMC) gels, the relevant fragments were excised from the gels, and purified using QIA-quick Gel extraction Kit (Qiagen, USA) according to the manufacturer's instructions. The isolated PCR DNA fragment was then ligated to the SacII-NotI digested and purified pMOL944. The ligation was performed overnight at 16° C. using 0.5 μg of each DNA fragment, 1 U of T4 DNA ligase and T4 ligase buffer (Boehringer Mannheim, Germany).

The ligation mixture was used to transform competent B. subtilis PL2306. The transformed cells were plated onto LBPG-10 μg/ml of Kanamycin-agar plates. After 18 hours incubation at 37° C. colonies were seen on plates. Several clones were analyzed by isolating plasmid DNA from overnight culture broth.

One such positive clone was restreaked several times on agar plates as used above, this clone was called MB878. The clone MB878 was grown overnight in TY-10 μg/ml Kanamycin at 37° C., and next day 1 ml of cells were used to isolate plasmid from the cells using the Qiaprep Spin Plasmid Miniprep Kit #27106 according to the manufacturers recommendations for B. subtilis plasmid preparations.

Construction of the Humicola insolens cDNA Library

The adapted, ds cDNAs were recovered by centrifugation, washed in 70% EtOH and resuspended in 25 ml DIW. Prior to large-scale library ligation, four test ligations were carried out in 10 ml of ligation buffer (same as above) each containing 1 ml ds cDNA (reaction tubes #1-#3), 2 units of T4 ligase (Invitrogen) and 50 ng (tube #1), 100 ng (tube #2) and 200 ng (tubes #3 and #4) Bst XI cleaved pYES 2.0 vector (Invitrogen).

Expression Cloning in Saccharomyces Cerevisiae of beta-1,4 Mannanase cDNA from Humicola Insolens

One ml aliquots of purified plasmid DNA (100 ng/ml) from individual pools were electroporated (200 W, 1.5 kV, 25 mF) into 40 ml of electrocompetent S. cerevisiae W3124 (MATa; ura 3-52; leu 2-3, 112; his 3-D200; pep 4-1137; prc1: :HIS3, prb1: :LEU2; cir+) cells (OD600=1.5 in 500 ml YPD, washed twice in cold DIW, once in cold 1 M sorbitol, resuspended in 0.5 ml 1 M Becker & Guarante, 1991). After addition of 1 ml 1 M cold sorbitol, 80 ml aliquots were plated on SC+glucose−uracil to give 250-400 colony forming units per plate and incubated at 30° C. for 3-5 days. The plates were replicated on SC+galactose−uracil plates, containing AZC1-galactomannan (MegaZyme, Australia) incorporated in the agar plates. In total, ca. 50,000 yeast colonies from the H. insolens library were screened for mannanase-positive clones.

The positive clones were identified by the formation of blue hydrolysis halos around the corresponding yeast colonies. The clones were obtained as single colonies, the cDNA inserts were amplified directly from yeast cell lysates using biotinylated pYES 2.0 polylinker primers, purified by magnetic beads (Dynabead M-280, Dynal) system and characterized individually by sequencing the 5′-end of each cDNA clone using the chain-termination method (Sanger et al., 1977) and the Sequenase system (United Sates Biochemical).

The mannanase-positive yeast colonies were incolulated into 20 ml YPD broth in a 50 ml tubes. The tubes were shaken for 2 days at 30° C., and the cells were harvested by centrifugation for 10 min. at 3000 rpm. Total yeast DNA was isolated according to WO 94/14953, dissolved in 50 ml of autoclaved water, and transformed into E. coli by electroporation as above. The insert-containing pYES 2.0 cDNA clones were rescued by plating on LB+ampicillin agar plates, the plasmid DNA was isolated from E. coli using standard procedures, and analyzed by digesting with restriction enzymes.

After 5 minutes 1 ml of 12 mg/ml BSA is added and incubation with gentle agitation continued for 1.5-2.5 hours at 37° C. until a large number of protoplasts is visible in a sample inspected under the microscope. The suspension is filtered through miracloth, the filtrate transferred to a sterile tube and overlayered with 5 ml of 0.6 M sorbitol, 100 mM Tris-HC1, pH=7.0. Centriguation is performed for 15 minutes at 100 g and the protoplasts are collected from the top of the MgSO₄ cushion. 2 volumes of STC are added to the protoplast suspension and the mixture is centrifugated for 5 minutes at 1000 g. The protoplast pellet is resuspended in 3 ml of STC and repelleted. This is repeated. Finally the protoplasts are resuspended in 0.2-1 ml of STC. 100 μl of protoplast suspension is mixed with 5-25 μg of the appropriate DNA in 10 μl of STC. Protoplasts are mixed with p3SR2 (an A. nidulans amdS gene carrying plasmid). The mixture is left at room temperature for 25 minutes. 0.2 ml of 60% PEG 4000. 10 mM CaC1₂ and 10 mM Tris-HC1, pH 7.5 is added and carefully mixed (twice) and finally 0.85 ml of the same solution is added and carefully mixed. The mixture is left at room temperature for 25 minutes, spun at 2500 g for 15 minutes and the pellet is resuspended in 2 ml of 1.2 M sorbitol. After one more sedimentation the protoplasts are spread on the appropriate plates. Protoplasts are spread on minimal plates to inhibit background growth. After incubation for 4-7 days at 37° C. spores are picked and spread for single colonies. This procedure is repeated and spores of a single colony after the second re-isolation is stored as a defined transformant.

Purification of the Aspergillus Oryzae Transformants

Aspergillus oryzae colonies are purified through conidial spores on AmdS+-plates (+0,01% Triton X-100) and growth in YPM for 3 days at 30° C.

Identification of Mannanase-Positive Aspergillus Oryzae Transformants

The supernatants from the Aspergillus oryzae transformants were assayed for beta-1,4-mannanase activity on agar plates containing 0.2% AZC1-galactomannan (MegaZyme, Australia) as substrate. Positive transformants were identified by analyzing the plates for blue hydrolysis halos after 24 hours of incubation at 30° C.

SDS-PAGE Analysis

SDS-PAGE analysis of supernatnants from beta-1,4-mannanase producing Aspergillus oryzae transformants. The transformants were grown in 5 ml YPM for three days. 10 μl of supernatant was applied to 12% SDS-polyacrylamide gel which was subsequently stained with Coomassie Brilliant Blue.

Purification and Characterisation of the Humicola Insolens Mannanse

The gene was transformed into A. oryzae ads described above and the transformed strain was grown in a fermentor using standard medium of Maltose syrup, sucrose, MgSO₄ Ka₂PO₄ and K₂SO₄ and citric acid yeast extract and trace metals. Incubation for 6 days at 34° C. with air.

The fermentation broth (5000 ml) was harvested and the mycelium separated from the liquid by filtration. The clear liquid was concentrated on a filtron to 275 ml.

The mannanase was purified using Cationic chromatography. A S-Spharose column was equilibrated with 25 mM citric acid pH 4.0 and the mannanase bound to the column and was eluted using a sodium chloride gradient (0-0.5 M). The mannanase active fractions was pooled and the pH adjusted to 7.3. The 100 ml pooled mannanase was then concentrated to 5 ml with around 13 mg protein per ml and used for applications trials. For further purification 2 ml was applied to size chromatography on Superdex 200 in sodium acetate buffer pH 6.1. The mannase active fraction showed to equal stained bands in SDS-PAGE with a MW of 45 kDa and 38 kDa, indicating proteolytic degradation of the N-terminal non-catalytic domain.

The amino acid sequence of the mannanase enzyme, i.e. the translated DNA sequence, is shown in SEQ ID NO:14.

The DNA sequence of SEQ ID NO:13 codes for a signal peptide in positions 1 to 21. A domain of unknown function also found in other mannanases is represented in the amino acid sequence SEQ ID NO: 14 in positions 22 to 159 and the catalytic active domain is found in positions 160 to 488 of SEQ ID NO: 14.

Highest sequence homology was found to DICTYOGLOMUS THERMOPHILUM (49% identity); Mannanase sequence EMBL: AF013989 submitted by REEVES R. A., GIBBS M. D., BERGQUIST P. L. submitted in July 1997.

Molecular Weight: 38 kDa.

DSC in sodium acetate buffer pH 6.0 was 65°.

The pH activity profile using the ManU assay (incubation for 20 minutes at 40° C.) shows that the enzyme has optimum activity at pH 8.

Temperature optimum was found (using the ManU assay; Megazyme AZCL locust been gum as substrate) to be 70° C. at pH 10.

Immunological properties: Rabbit polyclonal monospecific serum was raised against the highly purified cloned mannanase using conventional techniques at the Danish company DAKO. The serum formed a nice single precipitate in agarose gels with the crude non purified mannanase of the invention.

EXAMPLE 15 Wash Evaluation of Humicola Insolens Family 26 Mannanase

Wash performance was evaluated by washing locust bean gum coated swatches in a detergent solution with the mannanase of the invention. After wash the effect were visualised by soiling the swatches with iron oxide.

Preparation of locust bean gum swatches: Clean cotton swatches were soaked in a solution of 2 g/l locust bean gum and dried overnight at room temperature. The swatches were prewashed in water and dried again.

Wash: Small circular locust bean gum swatches were placed in a beaker with 6,7 g/l Ariel Futur liquid in 15° dH water and incubated for 30 min at 40° C. with magnetic stirring. The swatches were rinsed in tap water and dried.

Soiling: The swatches were placed in a beaker with 0.25 g/l Fe₂O₃ and stirred for 3 min. The swatches were rinsed in tap water and dried.

Evaluation: Remission of the swatches was measured at 440 nm using a MacBeth ColorEye 7000 remission spectrophotometer.

The results are expressed as delta remission=(R_(after wash)−R_(before wash))_(enzyme)−(R_(after wash)−R_(before wash))_(control), where R is the remission at 440 nm.

The mannanase of this invention is clearly effective on locust bean gum swatches with a wash performance slightly better than the control mannanase from Bacillus sp. I633.

Wash performance of Humicola insolens family 26 mannanase compared to the mannanase from Bacillus sp. I633 (examples 1-3) given as delta remission values:
